Choices columns

Artikel
09/09/2023

Customizers can define a column that allows selection of multiple options. The MultiSelectPicklistAttributeMetadata class defines a column type that inherits from the EnumAttributeMetadata class. Just like the PicklistAttributeMetadata class, this column includes an OptionSetMetadata.Options property that contains the valid options for the column. The difference is that the values you get or set are an OptionSetValueCollection type that contains an array of integers representing the selected options. Formatted values for this column are a semi-colon separated string containing the labels of the selected options.

Note

Only the publisher of a managed solution can import changes that delete an option from a global option set. This includes Microsoft published solutions such as the out of box global option sets. In order to make a change to the option sets, an Upgrade must be made to the solution that added the option set. More information: Upgrade or update a solution. Users can manually delete an option in their environment if they are unable to modify the solution or contact the solution publisher, but this must be done on every environment manually.

With the Web API, this column is defined using the MultiSelectPicklistAttributeMetadata EntityType.

Just like choices columns, there's technically no upper limit on the number of options that can be defined. Usability considerations should be applied as the limiting factor. However only 150 options can be selected for a single column. Also, a default value can't be set.

Setting choices values

The following examples show how to set choices values for a column named sample_outdooractivities added to the contact table.

Web API
SDK for .NET

With the Web API, you set the values by passing a string containing comma separated number values:

Request:

POST [organization uri]/api/data/v9.0/contacts HTTP/1.1
Accept: application/json
Content-Type: application/json; charset=utf-8
OData-MaxVersion: 4.0
OData-Version: 4.0

{
    "@odata.type": "Microsoft.Dynamics.CRM.contact",
    "firstname": "Wayne",
    "lastname": "Yarborough",
    "sample_outdooractivities": "1, 9"
}

Response:

HTTP/1.1 204 No Content
OData-Version: 4.0
OData-EntityId: [organization uri]/api/data/v9.0/contacts(0c67748a-b78d-e711-811c-000d3a75bdf1)

With the SDK for .NET, use the OptionSetValueCollection to set values for this column:


string conn = $@"
    Url = {url};
    AuthType = OAuth;
    UserName = {userName};
    Password = {password};
    AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d;
    RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97;
    LoginPrompt=Auto;
    RequireNewInstance = True";

var service = new CrmServiceClient(conn);
// var service = new ServiceClient(conn);

OptionSetValueCollection activities = new OptionSetValueCollection();
activities.Add(new OptionSetValue(1)); //Swimming
activities.Add(new OptionSetValue(9)); //Camping

Contact contact = new Contact();
contact["firstname"] = "Wayne";
contact["lastname"] = "Yarborough";
contact["sample_outdooractivities"] = activities;

service.Create(contact);

Query data from choices

Two new condition operators have been added to support querying values in choices:

Web API	FetchXml	ConditionOperator
ContainValues	`contain-values`	ContainValues
DoesNotContainValues	`not-contain-values`	DoesNotContainValues

Note

These operators depend on full-text indexing to be applied on the database tables that store the multiple values. There is some latentcy after new records are created and the full-text index takes effect. You may need to wait several seconds after new records are created before filters using these operators can evaluate the values.

Other existing condition operators that can be used with this type of column include the following:

Web API	FetchXml	ConditionOperator
`eq`	`eq`	Equal
`ne`	`neq`	NotEqual
`not null`	`not-null`	NotNull
`eq null`	`null`	Null
In	`in`	In
NotIn	`not-in`	NotIn

The following examples show using the ContainValues and DoesNotContainValues operators against the following data set on choices column named sample_outdooractivities on the contact table.

Choices `sample_outdooractivities` values

Value	Label
1	Swimming
2	Hiking
3	Mountain Climbing
4	Fishing
5	Hunting
6	Running
7	Boating
8	Skiing
9	Camping

Contact table values

`fullname`	'sample_outdooractivities'
Wayne Yarborough	1,9
Monte Orton	2
Randal Maple	4
Hiram Mundy	2,3,8,9
Barbara Weber	1,4,7
Georgette Sullivan	4,5,9
Verna Kennedy	2,4,9
Marvin Bracken	1,2,8,9

Web API
SDK for .NET

This example shows the use of the ContainValues query function to return all the contacts who like hiking. Notice how the text of the options is returned as annotations due to the odata.include-annotations="OData.Community.Display.V1.FormattedValue" preference applied.

Example code using FetchXml

The following code shows the use of FetchXml with Web API and SDK for .NET.

This sample shows the use of the not-contain-values using FetchExpression using IOrganizationService.RetrieveMultiple.

//Retrieving contacts who do not like hiking:

                     </fetch>";
FetchExpression doesNotLikeHiking = new FetchExpression(fetchXml);

EntityCollection nonHikers = service.RetrieveMultiple(doesNotLikeHiking);

Console.WriteLine("\nContacts who do not like Hiking");
Console.WriteLine("===============================");
foreach (Contact contact in nonHikers.Entities)
{
    string values = (contact["sample_outdooractivities"] == null) ? "null" : contact.FormattedValues["sample_outdooractivities"];
    Console.WriteLine("{0} {1}", contact.FullName, values);

Create choices with code

The easiest way to create choices is to use the column editor in the customization tools. More information: How to create and edit columns

But if you need to automate creation of this kind of column you can use C# code like the following with the SDK for .NET that creates choices to allow choices of outdoor activities to the contact table. More information: Create columns

private const int _languageCode = 1033; //English

MultiSelectPicklistAttributeMetadata outDoorActivitiesAttribute = new MultiSelectPicklistAttributeMetadata()
{
SchemaName = "sample_OutdoorActivities",
LogicalName = "sample_outdooractivities",
DisplayName = new Label("Outdoor activities", _languageCode),
RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
Description = new Label("Outdoor activities that the contact likes.", _languageCode),
OptionSet = new OptionSetMetadata()
    {
        IsGlobal = false,
        OptionSetType = OptionSetType.Picklist,
        Options = {
            new OptionMetadata(new Label("Swimming",_languageCode),1),
            new OptionMetadata(new Label("Hiking",_languageCode),2),
            new OptionMetadata(new Label("Mountain Climbing",_languageCode),3),
            new OptionMetadata(new Label("Fishing",_languageCode),4),
            new OptionMetadata(new Label("Hunting",_languageCode),5),
            new OptionMetadata(new Label("Running",_languageCode),6),
            new OptionMetadata(new Label("Boating",_languageCode),7),
            new OptionMetadata(new Label("Skiing",_languageCode),8),
            new OptionMetadata(new Label("Camping",_languageCode),9)}
    }
};

CreateAttributeRequest createAttributeRequest = new CreateAttributeRequest
{
    EntityName = "contact",
    Attribute = outDoorActivitiesAttribute
};

var response = (CreateAttributeResponse)service.Execute(createAttributeRequest);
